Although glucose molecules constantly diffuse into a red blo

Although glucose molecules constantly diffuse into a red blood cell along their concentration gradient, equilibrium is never reached and a steep concentration gradient is a continually maintained. What causes this? The active transport of glucose The rapid and continuous addition of phosphates onto the glucose molecules The ability of the cell to engulf glucose by pinocytosis The continuous excretion of glucose from other parts of the cell The very fast turnover rate of glucose metabolism

Solution

The correct answer is D. The continuous excretion of glucose from other part of the cell.

Glycolysis is a continuous process where glucose is constantly broken down to two molecules of pyruvate with the release of ATP and NADH. This process is the initial source of fuel for our body. As a result of which equilibrium is never reached in case of diffusion of the glucose molecule.
